DALLAS—A faceoff that could define the future of the Senate has ended with a defeat for Sen. John Cornyn (R-Texas) at the hands of Texas Attorney General Ken Paxton, who benefited from a late endorsement by President Donald Trump.
The Associated Press called the race for Paxton at 9 p.m. ET in the May 26 election that caps off the most expensive Senate primary in history.
